----------------------------------------
Summary: JournalStorageManager::stopReplication can deadlock while
stopping
Key: ARTEMIS-2347
URL: https://issues.apache.org/jira/browse/ARTEMIS-2347
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Affects Versions: 2.8.1
Reporter: Francesco Nigro
Fix For: 2.9.0
Attachments: deadlock_stacktrace.txt
JournalStorageManager::stopReplication needs to:
# acquires the manager write lock
# acquires (if any) large message intrinsic locks during
performCachedLargeMessageDeletes
# acquires the manager read lock on confirmPendingLargeMessage
JournalStorageManager::stop needs to:
# acquires (if any) large message intrinsic locks during
performCachedLargeMessageDeletes
# acquires the manager read lock on confirmPendingLargeMessage
A racing call to JournalStorageManager::stopReplication while stopping could
deadlock
the broker:
# JournalStorageManager::stop acquires a large message intrinsic locks during
performCachedLargeMessageDeletes
# JournalStorageManager::stopReplication acquires the manager write lock
# JournalStorageManager::stop wait is blocked on the manager write lock before
releasing the lock on large message
# JournalStorageManager::stopReplication is blocked on the large message
intrinsic lock before releasing the manager write lock
# deadlock occurred: none can proceed
